Australia’s Department of Immigration has inadvertently disclosed personal data on 10,000 asylum seekers, raising privacy concerns for a group that has every reason to keep a low profile.

The Guardianreports that information ranging from names to nationalities to locations in detention camps was mistakenly published on the department’s public website. The Guardianinformed officials of the breach before breaking the news story.

Immigration Minister Scott Morrison called the incident “unacceptable” and promised an independent investigation, according to Reuters. The error raises questions over whether any of those listed could now be repatriated, given that they may face reprisals for the very act of seeking asylum.
